Before any processes can begin, you need to find your mod podge image that can be transferred. The material or image needs to be porous as well as flexible to be usable with the glue. In other words, you need to use a substance that can absorb the glue through its porous texture. Your Mod Podge glue will not work on material that is not porous, flexible, or thin.
Mod Podge Thin Materials

Make sure the material you are transferring to your mod podge material is smooth with a clean and leveled surface. If your surfaces of the mod podge paper are not cleaned or the surface has any obstructions like dirt, sand, or debris, then your mod podge seal will fail to penetrate the surfaces and may capture bubbles and partially ruin your mod podge transfer. By using an old credit card and gently scraping it across both surfaces that will be used should remove any harmful debris. By lifting the flat surface to eye level and viewed under a bright light any surface irregularities can be easily observed before a seal is applied.
When applying the mod podge to any surface, paper, or wood, that will be the foundation of your work, use a brush that applies the mod podge to every surface, corner, and side of the surface. After you apply glue to every part of the surface, your transferred object will form a safe surface for a bond to form between the glue and the object.
Measure out only the amount of the material you need to transfer the foundation. Restrict the size of transferring content to the full scope of your mod podge base. Scoping your image is especially true if you are using a photo that has been transferred to a piece of paper. If you are going to use a family photo for your mod podge, you need to move it to a regular sheet of paper.
Preparing Photos for Transfer
Mod Podge artists recommend bringing your photo to a printer or photoshop and have it transferred to a regular sheet of paper and have the image copied in reverse image format. The reverse image will again reverse after it is placed face down onto the transferred surface. If your chosen material is a photo, it needs to be turned over on the foundation photo down and then covered entirely with mod podge. Note of caution: a photo image should have between 24-72 hours of dry time before it is peeled off. The more time you give to the image to dry, the more time the mod podge can seal the transferred image onto the surface.
Once your glue has been applied to the back of your transfer image or material, lay it flat on your mod podge foundation with the glue to form the bonding agent between the transferred material and your mod podge foundation.
Remove any bubbles that may have formed between the foundation and the material when the material was transferred to the base. You can use the same old credit card or a brayer to roll over your mod podge image to create a naturally flat surface over the whole surface of your mod podge foundation. After all the bubbles have been removed, then an extra coat of mod podge can be applied to the surface of the material. Note of clarification: since the mod podge acts as a glue, a sealer, and as a finisher, the mod podge is often used repeatedly on a surface for different reasons.
Creating Multiple Layers
After all of your work on your original transfer has been completed, your mod podge artwork is complete. Many mod podge artists continue to work on the same piece of artwork by adding extra layers to their original mod podge art. This process is like a visual counterpoint, which adds dimension to the mod podge art and it can be completed over days, weeks, and even months. The same tips above need to be applied (adding multiple images is not recommended) after each iteration and each new material added to your original mod podge art piece.
